Bug description:"last month" in date does not right on March 30th
Description:
------------
On March 30th and 31th the date function does not work correctly. If you
work with date("m")-1 the result is not 02 for the month. You get 03 for
the month but 02 for the day!!
If you change the system clock to another date the funtion works correctly.
See code below.
If you set the clock to Apr 30th and use date('m')-2 you get the same wrong
result.
Test script:
---------------
echo "<br>today: ". $today = mktime(0, 0, 0, date("m") , date("d"),
date("Y"));
echo "<br>". date('d.m.Y', $today);
echo "<br>";
echo "<br>tomorrow: ". $tomorrow = mktime(0, 0, 0, date("m") ,
date("d")+1, date("Y"));
echo "<br>". date('d.m.Y', $tomorrow);
echo "<br>";
echo "<br>last1month: ". $lastmonth = mktime(0, 0, 0, date("m")-1,
date("d"), date("Y"));
echo "<br>". date('d.m.Y', $lastmonth);
echo "<br>";
echo "<br>last2month: ". $lastmonth = mktime(0, 0, 0, date("m")-2,
date("d"), date("Y"));
echo "<br>". date('d.m.Y', $lastmonth);
echo "<br>";
echo "<br>last3month: ". $lastmonth = mktime(0, 0, 0, date("m")-3,
date("d"), date("Y"));
echo "<br>". date('d.m.Y', $lastmonth);
echo "<br>";
Expected result:
----------------
30.02.2010
Actual result:
--------------
02.03.2010
